bad backup status for VM

[tszczesn]

Hello.

One of my VMs has pemanent "active backup" status.
Command "info backup" from 'monitor' tab shows

# info backupBackup status: error - vma_queue_write: write error - Broken pipe
Start time: Wed Aug 12 22:30:06 2026
End time: Wed Aug 12 23:15:25 2026
Backup file: /dev/fdname/backup
Backup uuid: d001b9e1-09ea-44a7-83e0-aee91f541bf1
Total size: 2574833434624
Transferred bytes: 174644789248 (6%)
Zero bytes: 107190841344 (4%)
Reused bytes: 0 (0%)

VM works normally, but I can't do enything - new backup, migration to another node etc.

command 'backup_cancel' from 'monitor' tab does nothing, command 'vzdump 100 --storage backup --stop 1' does not work:

INFO: starting new backup job: vzdump 100 --storage backup --stop 1
INFO: Starting Backup of VM 100 (qemu)
INFO: Backup started at 2026-08-14 16:42:31

INFO: Failed at 2026-08-14 16:42:31
INFO: Backup job finished with errors

job errors

How can I remove this fake backup status?

You can remove the lock, which seems to be erroneously left behind: https://forum.proxmox.com/threads/vm-is-locked.177912/post-824222

Can you check:
grep lock /etc/pve/qemu-server/100.conf

And also:
ps aux | grep -E 'vzdump|qemu.*-id 100' | grep -v grep

No, there was no active vzdump process, and lock line exists in grep lock /etc/pve/qemu-server/100.conf.

qm unlock 100 works great, everything now is OK.
